CONDENSER.

densers, and the invention has for its object to provide mechanism in connection with the central condenser used in dry systems of vacuum pans for granulating sugar for preventing the vapors from interfering ,with the independent action of the several pans. In the drawings z-Figure 1 is a side view of the system with the condenser in section, Fig. 2 is a section on theline 2-2 of Fig. 41, and Fig. 3 is a top plan view of the condenser with the cover removed.

In the present embodiment of. the invention, the condenser comprises a' shell 1 of substantially cylindrical form having a hopper bottom 2 and a cover 3, and the shell is pro? vided with oppositely arranged inlet nipples 4.and 5, respectively, for connection with the pans 6 and 7. The discharge pipe 8 is connected with the lower end of the hopper bottom, the said bottom having `an .outletas shown, communicating with the discharge pipe.

The cover 3 is provided with a nipple 9 at vits center for connection with 'an air or vacuum pumpof the usual construction, and the shell is provided at its topand near the cover with an inlet pipe 10, the said pipe being threaded into a nipple 11 in the wall of the shell.

The pipe 10 leads from a suitable of water supply for supplying water to the trough 12,. which is arranged at the level of the pipe, and encircles the shell within the same. The inner wall 13 of this trough is toothed. or jagged as shown at its upperl end, and the trough is supported by an internal rib 14 on the shell wall, the said rib extending inwardly below the bottom of the trough.

Patented Aug. 22, 1916,

Application led December 29, 1915. Serial No. 69,185.

A plate 18 is supported between the troughs, the plate having a diameter a little i greater than the internal opening within the troughs. That is, the plate 18 is of such slze that when supported at the axis of the s hell, the edge of the plate will extend a llttle .beyond the walls 13 and 16 of the troughs, and will prevent the water flowing overthe inner wall 13 of the trough 124-13 from falling directly downward through the shell, and will deflect this water radially (lnltwlard, so that it will fall into the trough 6.

This plate 18 is' supported by bracket arms 19, extending upwardly from the inner wall 16 of the lower trough. The water owing from the inlet pipe will enter Vthe trough 12-13 and will pass over the toothed or jagged edge of the inner wall of the trough and will fall in a cylindrical formation on to the upper surface of the plate 18. The water will be deflected outwardly and will fall into the trough 15-16. From this trough the water will pass inward over the toothed or jagged upper'edge of the` inner wall 16 of the lower trough, and will fall in cylindrical formation through the lower part of the shell past the inlet nipples 4 and 5, and will strike thehopper bottom and will be deflected inwardly to How downward through the discharge pipe 8.

A baiile plate 20 is arranged diametrically of the shell below the plate 18, the said plate y2O extending the full diameter of the opening of the shell 1, and from the under surface of the plate 18 to near the lower end of the hopper bottom. The plate thus extends between the nipples 4 and 5, so that the vapors lowing in the condenser from either pan 6 or 7 cannot pass to the other pan to delay the formation of the grain, that is, to delay v'ranulation in the said other pan.

As the vapor arises from either pan itv will p ass upward through the valve 21, which connects the pan with the nipple 4 or 5, as the case may be, and will pass through the nipple into the condenser. This vapor will strike the baffle plate, and will be deiiected downwardly through the discharge pipe. The water falling from the troughs 12-13 the discharge pipe.

By arranging the baille plate 20 as shown, the time required in granulating a charge of syrup is much reduced, thereby greatly increasing the capacity of the pan. The 11nsov , and 15-16 will condense the vapor, and will drive it down with the falling water through iprovement also eliminates the necessity for stopping the mills, because of the excessive i of the 'evaporating apparatus.

It will be evident that while the invention is more especially adapted for the vacuum pans used in the sugar industry, it is also applicable to any system, using two or more vacuum pans for boiling under pressure below atmospheric. l

It will be evident from an inspection of Fig. 2 of the drawing, that the baffle plate 20 extends the full diameter of the condenser casing, and the edges of the battle' plate are notched as indicated at 21, to receive thetroughs 15-16. The lower end of the battle plate is beveled at each corner to lit the' hopper bottom 2and the baiile plate terminates just above the opening of the bottom.

We claim i 1. In a vacuum evaporating system and in combination, a plurality of vacuum pans, a condenser having a `body portion provided with inlets near its bottom and on opposite sides to which the vacuum pans .are con.-

nected, a discharge outlet at its lower end, an outlet nipple at its top for connection with the vacuum pump and having a plurality of water troughs one near the top and one above the inlet nipple@ and a baffle plate supported above the lowermost trough and between the same and the uppermost trough for deflecting the falling water from the upper trough into the lower trough, and a second baffle plate depending from the firstnamed plate between the inlets for prevent-- ing the Vapor from either pan passing directly into the other pan. Y

2. In a vacuum evaporating systemand in combination, a plurality of vacuum pans, a condenser having inlets near its bottom t0 which the pans are connected, and a baille plate supported between the inlets for pre.

venting the passage of the vapor from either pan directly to the other pan.

3.A In a vacuum evaporatingsystem and in combination, a plurality of vacuum pans, a.

condenser having inlets to which the pans are connected, and a baile plate within the condenser and between the inlets to prevent the vapor from either pan passing directly into the other pan. 1
